Hi Rod,
I think you are looking in the wrong places. This is and has been a common problem for several years with earlier versions of Windows. Some versions of Windows come with
SYSTEM RESTORE or SHADOW COPY automatically set to enabled, which is why you can't reclaim all of your storage space. Win7 for instance comes with
SYSTEM RESTORE enabled and set to on. Other versions of Windows such as XP, Vista, Win8/8.1 do not; they come disabled and turned off. The owner of the computer has to go in and enable
SYSTEM RESTORE to have it working. On the machines I've tested with Win10, this is also enabled and set to on. That means that a portion of your C: drive is automatically reserved for
SYSTEM RESTORE snapshots that allow you quickly reset your computer should you download a bad driver or a nasty virus that locks your computer up.
The good news, is that you can manually disable
SYSTEM RESTORE on your Win10; let us know if you need help doing this, I think I saw a good instruction link here the last few days on how to do this. It's pretty easy.
SYSTEM RESTORE is set to use a default amount of 8% of your disk space for this backup file. For example, on a 1TB hard drive, this is about 80GB or so. On a 100GB drive, 8GB, which is a much bigger chunk. If you are on a smaller drive, and space is at a premium you can adjust the percentage of disk space that Windows allocates for your
SYSTEM RESTORE file. You can decrease it to 5% or increase it to 15% for example. Or you can disable it entirely, and then reclaim that extra disk space.
The bad news is that if you disable your
SYSTEM RESTORE feature, which I do not recommend doing, you will lose your ability to recover from catastrophic events (faulty driver updates & viruses) in a short period of time. A few hours versus weeks for a manual Win10 rebuild. There are other methods you can use alternatively, such as creating backup Image Clone files using products such as
Macrium Reflect or Acronis TrueImage. For this you will need a second internal hard drive or an external USB hard drive depending on whether or not you have a desktop PC or a laptop (most laptops only have 1 internal drive). You can also do online to Cloud image recovery using fee-based Cloud providers such as
Carbonite and CrashPlan. These run about $60 a year. Lastly, and most expensive is to upgrade your existing PC if you have a desktop, and install a RAID PCI card controller and use RAID 0, 5, or 10 with multiple disk drives to recover from a catastrophic Windows failure. [
clearly a much more expensive and technically challenging effort to implement than the software-based SYSTEM RESTORE].
This is probably more information than you wanted or needed, but I feel it's important to let people know they have alternatives to running
SYSTEM RESTORE (which you can tell I really like). Reclaiming that space may be useful in the short run, but if your Windows crashes, and you have a project to get out in 1-2 days, you had better have an alternative to repair it quickly, because otherwise you are looking at 1-3 weeks for a complete rebuild and that would be very bad for you.
Hope this proves helpful,
